Izinga lomoya ngaphakathi ezindlini, ezikoleni, nakwezinye izakhiwo lingaba isici esibalulekile sempilo yakho nendawo ezungezile.

Ikhwalithi Yomoya Wasendlini Emahhovisi nakwezinye Izakhiwo Ezinkulu

I-Radon

Igesi ye-radon yenzeka ngokwemvelo futhi ingabangela umdlavuza wamaphaphu.Ukuhlola i-radon kulula, futhi ukulungiswa kwamazinga aphakeme kuyatholakala.

• Umdlavuza wamaphaphu ubulala izinkulungwane zabantu baseMelika minyaka yonke.Ukubhema, i-radon, nentuthu kagwayi yizona zimbangela eziphambili zomdlavuza wamaphaphu.Nakuba umdlavuza wamaphaphu ungelapheka, izinga lokusinda lingelinye eliphansi kakhulu kulabo abanomdlavuza.Kusukela ngesikhathi sokuxilongwa, phakathi kwamaphesenti angu-11 no-15 alabo abahlushwayo bazophila ngaphezu kweminyaka emihlanu, kuye ngezici zezibalo.Ezimweni eziningi umdlavuza wamaphaphu ungavinjelwa.
• Ukubhema kuyimbangela ehamba phambili yomdlavuza wamaphaphu.Ukubhema kubangela ukufa komdlavuza okulinganiselwa ku-160,000* e-US minyaka yonke (American Cancer Society, 2004).Futhi izinga phakathi kwabesifazane liyakhuphuka.Ngo-January 11, 1964, uDkt. Luther L. Terry, ngaleso sikhathi owayenguDokotela Omkhulu Wokuhlinza Wase-US, wakhipha isixwayiso sokuqala mayelana nokuhlobana phakathi kokubhema nomdlavuza wamaphaphu.Umdlavuza wamaphaphu manje usudlula umdlavuza webele njengembangela yokuqala yokufa kwabesifazane.Umuntu obhemayo naye ochayeke ku-radon unengozi enkulu kakhulu yomdlavuza wamaphaphu.
• I-radon iyimbangela yokuqala yomdlavuza wamaphaphu kubantu abangabhemi, ngokwezilinganiso ze-EPA.Sekukonke, i-radon iyimbangela yesibili ehamba phambili yomdlavuza wamaphaphu.I-Radon inesibopho sokufa komdlavuza wamaphaphu okungaba ngu-21,000 minyaka yonke.Cishe i-2,900 yalokhu kufa kwenzeka kubantu abangakaze babheme.

I-carbon monoxide

Ubuthi be-carbon monoxide yimbangela yokufa engagwemeka.

I-Carbon monoxide (CO), igesi engenaphunga, engenambala.Ikhiqizwa noma nini lapho kushiswa amafutha emvelo futhi ingabangela ukugula nokufa kungazelelwe.I-CDC isebenza nozakwethu kazwelonke, wesifunda, wendawo, nabanye ukuze baqwashise mayelana nobuthi be-CO kanye nokuqapha idatha ehlobene nokugula okuhlobene ne-CO kanye nokubhekwa kokushona e-US.

Intuthu kagwayi yemvelo / intuthu kagwayi

Intuthu kagwayi iyingozi ezinsaneni, ezinganeni nakubantu abadala.

• Alikho izinga eliphephile lokuchayeka entuthuni kagwayi.Abantu abangabhemi abachayeka egwayi kagwayi, ngisho isikhathi esifushane, bangaba nemiphumela eyingozi empilweni.1,2,3
• Kubantu abadala abangabhemi, ukuhogela intuthu kagwayi kungabangela isifo senhliziyo, unhlangothi, umdlavuza wamaphaphu nezinye izifo.Kungase futhi kubangele ukufa ngaphambi kwesikhathi.1,2,3
• Ukubhema kukagwayi kungabangela imiphumela emibi yezempilo yokuzala kwabesifazane, kuhlanganise nesisindo sokuzalwa esiphansi.1,3
• Ezinganeni, ukuchayeka kwentuthu kagwayi kungabangela izifo zokuphefumula, izifo ezindlebeni, nokuhlaselwa yisifuba somoya.Ezinganeni, ukubhema kukagwayi kungabangela ukufa kwezingane ezisanda kuzalwa (SIDS).1,2,3
• Kusukela ngo-1964, abantu abangaba ngu-2 500 000 ababengabhemi bafa ngenxa yezinkinga zempilo ezibangelwa ukubhema ugwayi.1
• Imiphumela yokuchayeka kwentuthu kagwayi emzimbeni ngokushesha.1,3 Ukuchayeka kwentuthu kagwayi kungaveza imiphumela eyingozi yokuvuvukala nokuphefumula phakathi nemizuzu engu-60 yokuchayeka okungahlala okungenani amahora amathathu ngemva kokuchayeka.4
